Design specifications

The [CT Filtron] (http://ceramicatamakloe.net/filtron/) filtering element is made from porous clay that once fired, permits water to pass through but not dirt and the harmful bacteria.The ceramic filtering element is also treated with silver nanoparticles.

Extracts of [test results] (http://www.steppingstonesforafrica.org/wp-content/uploads/CT%20FILTRON%20BROCHURE.pdf “http://www.steppingstonesforafrica.org/wp-content/uploads/CT%20FILTRON%20BROCHURE.pdf”) from the Water Research Institute of the Council for Scientific and Industrial Research (CSIR) Ghana indicate elimination of Guinea Worm, Cholera, E. Coli and other listed bacteria.

The results from Dept. Of Microbiology, University of Ghana Medical School indicate that the CT Filtron is effective in removal of pathogenic parasitic protozoa, other macroscopic organisms and debris from water.

CT Filtron removed 99.5% of total coliform when measured by [membrane filtration](https://dspace.mit.edu/handle/1721.1/34669#files-area).
